Description of change
To optimize random reads we don't start the second request until half of the first one was read as the second request may not be needed. This results in a significant improvement of read throughput for random reads, which is most noticeable for express:
24.8287109375 MiB/s)14.17802734375 MiB/s)Relevant issues: N/A
Does this change impact existing behavior?
It doesn't change behavior but impacts performance of random reads.
Does this change need a changelog entry in any of the crates?
No changelog entry required.
